Vanderbilt Family Treasures Sell in Phillips’s $17 M. Jewelry Auction
58Nov. 12, 2025
Twelve lots offering storied jewels from the Vanderbilt family sold out in Phillips’s “Geneva Jewels Auction” on Monday, making up a significant portion of the total of CHF 13.7 million (around $17 million) raked in by the sale. Ninety-six of 113 total lots sold, measuring in for a 85-percent sell-through rate, and the results “attest to the enduring appeal of period jewels and the discerning eye of our international clients,” according to Phillips worldwide head of jewelry Benoît Repellin. The Vanderbilt family jewels brought in CHF 3.42 million ($4.25 million), four times the low estimate for the lots, and were led by “The Vanderbilt Sapphire,” a Gilded Age treasure featuring a 42-karat sugarloaf Kashmir sapphire and a diamond brooch crafted by Tiffany & Co. that sold for CHF 2.88 million ($3.57 million), above its estimate of $1 to $1.5 million.
